For EE's: diff btw 'magnetic' noise vs 'electric field' noise?! (pickups, shielding)

As someone who 6 months ago was new to oscilloscopes & can now use one well enough for guitar amp work - I'd highly suggest going the "real piece...

Completely agree with both recommendations here.

First, for LTSpice, the Windows interface is MUCH more friendly and has MUCH better documentation....

Actually I've already changed my mind - when I went back the next day & thought about it one more time, I realized there is enough of a frame, plus the...

Just to close this thread out (not that anybody was following it) - I had put this tape recorder aside while I did other things & just came back to it...

That piece of brown tongue-and-groove on the left, under the blue goop, looks like the laminate flooring they sell up here, a.k.a. "click-board."...

Interesting tests, thanks. Curious if it sounds better or worse when shielded? Or just different?

Also, were the spectrograms done with a mic...

It's not a big problem! I thought I made that pretty clear. But I admit that confuses the usual mindset brought to a forum, where generally posts are about...

More for them as care about "electrostatics" - possibly I did misdefine it, although you will find similar definitions in many places. For example...

[Usable Thought]

Are you sure? And would that really be the interesting part? Perhaps I used the word "electrostatics" incorrectly in bringing it up; or perhaps...

This is where things seem to get interesting.

To start with - and this is a very minor point - when you say "electromagnetic" that...

Pot stirred.

If I have time I may still mess around myself. I hear too many competing claims on this topic, always stated as God's truth, for...

Article says mains hum is electrostatic, not magnetic - implications for single coil

This is an example of some (but not all by any means)...

Thanks, yes, this seems possible. And I know about Kinman, Ilitch, etc. However at the moment my focus is not so much on existing solutions but on the underlying...

Actually my digging, based on pointers from Nick plus some other Googling I'd already done, is turning up some stuff that I find really interesting - phenomena...

[Usable Thought]

Thanks Nick - this is helpful. I am going to look up more info based on what you say (e.g. loop antennas & then again at how pickups work, in light of...

I've got a big interest in shielding guitars to reduce noise & have read a lot about it. I've only got humbuckers, but I'm thinking of getting a single...

So having lots of awake time at 3 a.m. these days, I did up a new signal tracer with 0.022uF blocking cap, and a JMF-style attenuator plus clamp to go with...

More accurate to say the manufacturers did market research, found "small/thin" was something consumers liked, then began pushing it on us &...
